Title: Production of magnetic head
Inventor: KURAKANE KIYOSHI
IPC: G11B5/23
Filed: 1984-02-24
Abstract: PURPOSE:To improve the reliability of a magnetic head with no breakdown of a gap by attaching a glass material having width equal to the desired gap width to a gap forming surface of a core member and heating up the glass material together with a reinforcement glass member to combine two core members and to increase the combining intensity. CONSTITUTION:A glass material 4 is attached to gap forming surfaces 2 and 3 of a core member 1 up to the thickness equal to the desired gap width. A core member 5 is joined to the material 4, and a reinforcement glass material 20 having the same fusing temperature as the material 4 is attached at a place near the press-contact part of the gap forming surface 2 between both core members. Both glass materials 4 and 20 are fused by heat to combine firmly the core members 1 and 5 to each other. Thus no crack is produced despite a cutting process applied to a part A with no gap breakdown caused in a working mode of a magnetic head. In this way, a magnetic head having high reliability is obtained with high production yield.

The medical fluid such as ammonium phosphate is sprayed from the medical fluid-spraying nozzle 4 of a manufacturing apparatus 5' for a zero-spangle to fine the crystal grains of a galvanized layer. At this time, apart from the medical fluid-blowing nozzle 4, the water-spraying nozzle 11 is disposed to the side closer to the hot-dip zinc coating bath 1 than the above nozzle to control the timing of the solidification in coating. By this method, the optimum cooling conditions of a sticking hot-dip galvanized layer is ensured to stably manufacture the zero-spangle galvanized steel sheet of high quality.

Abstract: PROBLEM TO BE SOLVED: To adjust an angle of a brake arm easily and accurately by providing a reference plate on a bottom of a cylinder of a hydraulic cylinder and adjusting an angle of the brake arm in a condition in which a piston is in contact with the reference plane. SOLUTION: A hydraulic cylinder 54 has a brake liquid supply hole 54k and a reference plane 54a in a bottom part of a cylinder main body 54b. Moreover, it is provided with a spring 54f which is an elastic member which pushes a piston 54c to reference plane 54a side. A mounting angle of a subarm 53 for a brake arm 51 is adjusted by a bolt with nut 52. The angle is adjusted in a condition in which the piston 54c is in contact with the reference plane 54a. Since a rear end of the piston 54c is pressed against the reference plane 54a by the spring 54f when the hydraulic cylinder 54 is not operated, the piston 54c can be precisely positioned for the cylinder main body 54b, and the travel of the piston 54c due to the vibration can be prevented by the spring 54f.

Filed: 1981-03-13
Abstract: PURPOSE:To eliminate the data transfer process between the files and to increase the processing performance and the response properties, by providing a control header which discriminate a new or old file in the process of the transfer. CONSTITUTION:In a block K, a control header is added to a file which is under the unitary control to produce the header information by which a time series file is treated in a random file way. In a block L, the branching elements to blocks M, N and P are decided based on the header information produced at the block K. The blocks M, N and P transfer the instantaneous value to each designated file by each header information. A block Q produces a file header after the transfer via one of the blocks M, N and P. Thus the control information is produced in case the so-called time series file is controlled at random.
